文摘

Sink and source components were measured regularly during sunflower achene filling. Phenotypic differences were created by N fertilization, plant density and cultivar. Bi-linear models were fitted to dry weight dynamics of sinks and sources. Nitrogen and plant density influenced rates and duration of these dynamics. Cultivar influenced the timing of source and sink dynamics. The ‘source’ chronology was: receptacles > stems > green leaves. The “sink” chronology was: receptacles > hulls > protein> oil.
